Tls Session Management Method In Supl-Based Positioning System
First Claim
1. A transport layer security (TLS) session management method in a system in which a terminal having a TLS session with a Home-SUPL Location Platform (H-SLP) receives a positioning service by roaming to a Visited-SLP (V-SLP), comprising:
- transmitting TLS session information, which has been used when the H-SLP sets a TLS session with the terminal, from the H-SLP to the V-SLP; and
using the TLS session information to set a new TLS connection for a location calculation between the terminal and the V-SLP.

Abstract
When a SET receives a positioning service from a V-SLP by performing a roaming from a H-SLP to the V-SLP in a SUPL-based positioning system, only a new TLS connection is generated using an abbreviated handshake protocol without generating anew TLS session after the roaming. That is, when opening a TLS session for ensuring security in a SUPL-based positioning method, in particular, when opening a new TLS session between the V-SLP (V-SPC) and the SET after opening the TLS session between the H-SLP and the SET, the key information having used in the previous TLS session is provided to the V-SLP to set a new TLS connection, thereby reducing a load of an entire system.

10. A TLS session management method in a roaming of a SUPL-based positioning system using a TLS comprising:
-
setting a TLS session between a terminal and a H-SLP, and transmitting a SUPL START message from the terminal and the H-SLP; transferring information related to the set TLS session from the H-SLP to a V-SLP to which the terminal roams; transferring information related to the V-SLP from the H-SLP to the terminal; and using the TLS session information to set a new TLS session between the terminal and the V-SLP in the TLS session. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A TLS session management method in a roaming of a SUPL-based positioning system using a TLS comprising:
-
setting a TLS session between a SUPL Enabled Terminal (SET) and a H-SLP; transmitting a SUPL START message from the SET to the H-SLP; when the H-SLP receives the SUPL START message, transmitting TLS session information to a V-SUPL Location Center (SLC) of a V-SLP through an RLP SSRLIR message; transferring the received TLS session information from the V-SLC to the V-SUPL Positioning Center (SPC) through an internal initialization; transmitting a session ID and a V-SPC address to perform the position calculation from the V-SLC to the H-SLP through an RLP SSRLIA message; transmitting the session ID and the V-SPC address through a message in response to the SUPL START message from the H-SLP to the SET; setting a new TLS connection using the TLS session information between the SET and the V-SPC; calculating the SET location by performing the SUPL positioning procedure between the V-SPC and the SET; and when the location of the SET is completely calculated, transmitting a SUPL END message from the V-SPC to the SET. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26)
